Interior walls are not made to handle contact with water, and they are not made to be submerged in water. If you experienced flooding inside your home that went up to your walls, you are going to have a big issue to deal with.
Generally, your interior walls are made of drywall. Drywall is designed to absorb water, not repel it. Drywall cannot handle exposure to water.
Open the Wall Cavity
The first thing you are going to want to do is to open the wall cavity. The exterior wall material is not the only thing you need to worry about drying out. You are going to want to dry out the entire wall cavity, including the framing and insulation, which requires opening the wall cavity. Opening the wall cavity will allow air to circulate, help dry things out, and help save some of the interior materials. To open up the cavity, you will need to break open the wall and remove the damaged drywall.
Get Rid of Damaged Insulation
Once you have removed the drywall and opened the air cavity, it is time to check out the insulation condition. Insulation tends to be extremely absorbent. It will take the water and hold it up against the wall's structural pieces, further extending the water damage. As such, you are going to want to get the remove the insulation as quickly as possible. You will not be able to salvage any wet insulation, and the sooner you remove it, the less damage will be caused to surrounding materials.
Inspect the Wallboards
Next, you are going to want to inspect the wallboards. If you moved fast enough removing the drywall and the insulation, the wallboards might still be okay. However, if the wallboards are wet, you will want to cut away all the damaged areas that are saturated with water. When cutting away the damage, cut a foot or two above where it looks like the water damage stopped to ensure you are removing all the water-damaged wallboard.
Water can wick up the wallboards and eventually damage your ceiling, which you want to prevent.
Be Aware of Safety Concerns
If you like in an older home, such as one that was built in the 1970s or earlier, you will want to be aware of the safety issues you may encounter. With older homes, you need to be aware of the risk of encountering lead materials. For example, you don't want to cut into and release lead into your home without the proper equipment in place.
If your home's interior walls are water damaged, you will need to work fast to prevent the spread of the damage. You need to remove damaged drywall to open the wall cavity. Then, you need to pull out damaged insulation and check the wallboards for damage as well. Proceed with caution if you are in an older home.
